Didn't find this one before. I wrote my own user-space-threading library called libwire. Mostly for not liking the malloc-everywhere approach so common everywhere. The tradeoffs are different and the code is more verbose at times but I

You can increase the define if you need more than 1024 fds but then the performance is getting very poor.

Back from the time I was obsessed with firewalls (having written one at work at the time) I started to write an IPTables firewall rule optimizer in a bid to speed up the rule processing. https://github.com/baruch/fwopt

In my work on improving performance of the Linux TCP stack (part of my involvement with HTCP) I never saw the congestion-control part in the performance monitoring. There are such long linked lists that one goes over that any small computat

OSv does something similar to Mirage it seems and is written in C++. They also can run different languages, I believe I saw lua support and they commercially target Java too.

Some feedback: What I'm missing in PC builders at shops is the ability to filter say the motherboard by the features. How do I know if the H61 is better than the G41? Once I selected an i3 why are you showing me AMD motherboards? do I

If it's only a sector that died on you in one disk the likelyhood that the equivalent sector in the RAID stripe also failed is fairly small[1]. The most often cited issues is with a full disk failure and then having a sector already de

What you describe is what is known as disk scrubbing, and indeed if you are operating a RAID device and it doesn't do disk scrubs every so often you are doing it wrong. Linux mdadm has this feature as well and in most distributions tha

I really thought I found something rather new as I've been looking for such a topic for some time now. But there is a sub-reddit for that http://www.reddit.com/r/CompressiveSensing/ Oh well, it is still inter

I'm working in EMC XtremIO, we do a high-performance enterprise storage which is a hit in the All-Flash-Array world. We do it in C and it's a game-changer in the enterprise storage world. EMC has essentially stopped saying the VMA

Any ideas what are the integration methods at the sender sides? They'd obviously need to collect the new id number and automatically find the current address. I'd also wonder if financial institutions can use such a service at all

I prefer to work in C over C++ (did both at different jobs), mostly does C but where I don't care just that much about performance (specific allocations of memory and the like) than I'm likely to prefer Go over C++. It's far

I was also inspired by Go channels and am working on a library in C that marries fibers, mostly blocking channels and a way to select on the channels. You can find it in http://Github.com/Baruch/libwire

Jamendo radios, mostly rock and lounge. It helps that English is not my mother tongue and so just a random song is unlikely to grab my attention too much. Known songs might very well distract me so I avoid my personal music collection.

There is also the topic of Cache Oblivious data structures. Sadly, I'm still trying to figure that one out but it looks like it could help. Both with the memory and cache access time disparities and it is claimed that also with the mem

I much prefer ReQL over SQL. It is much nicer, flows naturally in my opinion and is combine-able. I'm using this combination method in my rethink-miner tool to help me work with data to try and figure it out and I can make generic quer

It seems you are conflating two different topics here, one of splitting future titles and working order and the other of presenting things externally. Figure out now how you intend to split the roles between you and how you intend to work t

I've been working on Storage systems with multi-gigabytes of RAM where you still reason about your memory in much the same way. These systems have lots of RAM but properly intend to make use of all of it. I tend to prefer to allocate o

About reboot monitoring, I suggest to use kdump to dump the oops information and save it for later debugging and understanding of the issue. It may even be an uncorrectable memory or pcie error you are seeing and the info is logged in the o

ZFS would help to handle some of the failure types of SSDs. I doubt that it can help in the case of a multiple disk failures due to a power failure. As for the original report, if you rely on your storage devices to survive a power outage y

I'm not quite sure what is so special here. It is a device, it has firmware, the firmware can be upgraded. The same is true for your HDD or SSD. Why is an SD Card any different? If someone hands you an SSD in an external enclosure do y

It's unlikely that the firmware region will be corrupted unless you are in the middle of a firmware upgrade. While with the variety of SSD and HDD failures I've seenis large and such a failure is not impossible it's one I&#x2

One main reason is that the SSDs do not store the data where you ask it for, it maps that location to any other location that it sees fit. That means it has an address-to-physical-location mapping that it maintains. If the SSD loses that ma
